I think if you were ultimately responsible for appointing someone a job with access to sensitive and or secret information then you would want to be sure that he had been granted the necessary security clearance.

Guess we will never know the truth.

Sorry to hear about your sons "friend" guess what you are saying is that this "friend" knowingly sold your son a duff motor.

I always find that honesty is the best policy when selling a vehicle.

Any that I have sold over the years I point all the known faults so the buyer can make their decision.
